Klaczkiewicz, Wilmington, Del.,assignor to Beloit Eastern Corporation, Downingtown, Pa., a corporationof Delaware Filed Jan. 7, 1966, Ser. No. 519,206 13 Claims. (Cl. 242-66)This invention relates to improvements in drum winders for paper and thelike.

A principal object of the present invention is to improve upon the drumwinders heretofore in use for rewinding paper and the like, bysimplifying adjustability and maintenance of the winder and increasingthe efficiency thereof by improving upon the slides and supports for thecore shaft for the roll of paper,

Another object of the invention is to provide a new and improved drumwinder for rewinding paper and the like, in which the usual cantileveredcore shaft slides are replaced by slides slidably supported alongopposite sides of the center of the core shaft, and thereby providing agreater thrust capacity for-the core shaft and restriction in the endplay of the shaft.

A still further object of the invention is to provide a novel andimproved drum winder for rewinding paper and the like, in which the coreshaft is rotatably supported intermediate the guides for the core shaftslides and a brake means is provided, controlling ascent of the coreshaft slides and simplifying the adjustability and replacement of thecore shaft.

Still another object of the invention is to improve upon the drumwinders for rewinding paper and the like by slidably guiding the coreslides along opposite sides of the slides and suspending the slides fromthe centers thereof, and providing detachable chucks for the core shaft,the centers of which are in alignment with the lines of suspensionthereof and intermediate the guides for the slides to simplify thereplacement and adjustability of the core shaft.

Still another object of the invention is to provide a simple andimproved form of drum Winder in which core shaft slides slidablysupported equal distances from the center of the core shaft, replace theusual cantilever slides, in which a control shaft for the slides tiesthe slides for movement together and is controlled by a brake,controlling ascent of the core shaft slides, and in which fluid pressurecylinder and piston means are provided for ad justably moving theslides, and interlocked with the brake for the control shaft for theslides.

A still further object of the invention is to provide a novel andimproved control for the rider roll of a drum winder having a simple andimproved form of counterweight which may readily be filled with shot tothe extent required to counterbalance the rider roll.

Still another object of the invention is to improve upon I the riderroll supports and counterweighting means for drum winders heretofore inuse by supporting the rider roll in slides slidably supported onopposite sides of the rider roll and vertically moved by fluid pressureoperated cylinder and piston means at each end of the rider roll, inwhich counterweights in the form of upwardly opening receptacles aremounted on the cylinder and piston means and may readily be loaded withshot and the like, to counterbalance the rider roll.

These and other objects of the invention will appear from time to timeas the following specification proceeds and with reference to theaccompanying drawings wherein:

FIGURE 6 is a sectional view line VI-VI of FIGURE 5.

In the embodiment of the invention illustrated in the drawings, I haveshown in phantom in FIGURES l, 2, 5 and 6 a drum winder 10 including abase 11, shown in phantom, and parallel spaced posts 12, 12 shown inphantom as extending upwardly of opposite sides of said base. The base11 carries bearing supports (not shown) for rotatably supporting a pairof spaced horizontally aligned Winder drums in a conventional manner.The base 11 may also form a support for a motor (not shown) andreduction gearing driven therefrom (not shown) for driving the winderdrums 13, 13.

The posts 12, 12 each have parallel spaced facing channeled guides 15,15 extending therealong (FIGURE 2) forming slidable guides for coreshaft slides 16, 16 and rider roll slides 17, 17 disposed above saidcore shaft slides and slidably movable along said guides.

As shown in FIGURES 1 and 2, each core shaft slide 16 is in the generalform of an elongated plate having a boss 18 extending outwardly of acentral upwardly opening recess formed in said slide and forming amounting for an eye bolt 19 having a flexible support and drive member,such as a drive chain 20 suitably connected to the eye thereof. Thechain 20 forms a support for the slides 16 and is connected thereto inalignment with the center of the core shaft and roll of paper beingwound thereon, and extends upwardly of said slide along a line disposedmidway between the guides 15, 15 over an idler sprocket 21 suitablyjournalled in a cap 22 for the post 12, extending along the outside ofsaid idler sprocket. The chain 20 extends from the top of the idlersprocket 21 about a sprocket 23 on the outer end of a control shaft 24suitably journalled in the cap 22. From thence the chain extendsdownwardly to an eye bolt 25 mounted on a horizontal leg 26 of an angleiron, the vertical leg of which is bolted or otherwise secured to afluid pressure operated cylinder 27, movable along a piston rod 29,fixed at its opposite ends. The piston rod 29 is mounted at its upperend in a flange 30 extending outwardly of the cap 22 for the post 12 andat its lower end in a shouldered portion 31 of the base 11. A secondflexible drive device in the form of a drive chain 32 is connected to aneye bolt 33 mounted in the leg 26 of the angle iron and extendsdownwardly therefrom about a direction changing idler sprocket 35 andupwardly therefrom to an ear 36 extending laterally of the slide 16, andis suitably connected thereto to lower the slide 16 as the cylinder 27moves upwardly along the piston rod 29.

The slide 16 is slidably guided along the channeled guides 15 onfollower rollers 37, 37 engaging the insides of legs or flanges 38, 38of the channeled guides 15, as

taken substantially along shown in FIGURE 2, the slides 16 also haveparallel spaced vertically extending ribs 39, 39 spaced inwardly ofopposite sides thereof and extending therealong. The ribs 39, 39 formabutments for retainer gibs 40, 40 extending vertically along saidslides and secured thereto as by machine screws 41. The retainer gibs 40have inwardly beveled engaging faces 42 slidably engaging correspondingfaces extending along the ends of the legs 38 and retaining said slides16 for vertical movement along the flanges 38, 38 of the channeledguides 15, 15.

The slide 16 has a rectangular boss 43 depending therefrom and extendinginwardly therefrom and forming a mounting for a piston rod 44 extensiblefrom and retractible within a cylinder 45. The cylinder 45 is shown inFIGURE 2 as being mounted on the outside of an outwardly extending bossportion 46 of the boss 43 as by machine screws 47. The piston rod 44 hasa core shaft chuck 48 journalled on the outer end thereof and engagingwithin the end of a core shaft 49, a fragment of which is shown inFIGURE 2. The core shaft 49 may be of a conventional form and may besurrounded by a tubular shell on which the web is wound.

The leading end of the paper web is thus threaded around the tubularshell of the core shaft and suitably clamped thereto. The rolls 13, 13are then driven to rotate the core shaft and shell so that a roll ofpaper will build up on said shell in contact with the winder drum 13,13. As the roll builds up on the core shaft 49, the paper building up onsaid core shaft riding on the nips between the winder drums 13, 13 willlift the slides 16, 16 along the guides 15, 15 extending along oppositeposts 12, 12, in cooperation with the cylinders 27, 27.

The core shaft chuck 48 and core shaft 49 mounted thereon are thusrotatable about coaxial axes midway between the guides 15, 15. The coreshaft slides 16, 16 are also slidably supported equal distances from thecenter of the core shaft to provide a rigid slidable support for theslides and core shaft, with a resultant greater thrust capacity and arestriction in end play along the axis of the core shaft.

The cylinders 27, 27 at opposite ends of the winder may thus serve toquickly raise the core shaft slides and may also serve to lower theslides under the control of the control shaft 24. The control shaft 24is suitably journalled in the caps 22 for the posts 12 at the topthereof and extends thereacross and is provided with a pair of parallelspaced flanges 50, 50 extending radially outwardly therefrom, having abrake 51 mounted in the space therebetween. The brake 51 may be aconventional diaphragm brake known to the trade as a Horton diaphragmbrake, so only herein shown and described generally. The brake includesa lower shoe 51a lined with a brake lining (not shown) engageable withthe periphery of the shaft 24. An upper shoe 52 is pivotally suspendedfrom a bracket 53 on a pivot pin 54. The bracket 53 is shown as beingsuitably mounted on and extending inwardly of an associated cap 22 for apost 12. The shoe 52 has lugs 55 extending outwardly from opposite endsthereof. The shoe 51a has corresponding lugs 56 extending outwardly ofopposite ends thereof. A separate rod 57 threaded at one end thereofextends through each lug 55 and the registering lug 56 and is secured tothe associated lug 55 as by nuts 59 engaging opposite sides of said lug.A compression spring 60 encircles each rod 57 and is interposed betweena collar 61 secured to said rod and the lug 56, to bias the brake shoe51a in on off position. A fluid pressure operated diaphragm 63 isconnected with the shoe 51a through a plunger 65, to apply the brake.

The brake 51 is interconnected in the fluid pressure circuit controllingoperation of the fluid pressure operated cylinders 27, to apply thebrake during raising movement of the slides 16, 16 and the core shaft 49and thereby cont-r01 movement of the slides 16, 16 and make it possibleto accurately stop the slides in a desired location. The brake may alsocontrol descent of the slides.

The rider roll slides 17, 17 are slidably guided in the guides 15, 15and are vertically moved along said guides by flexible drive devices,such as drive chains 66, operated by fluid pressure cylinders 67, havingpiston rods 68 extensible therefrom, as will hereinafter more clearlyappear as this specification proceeds.

As shown in FIGURES 1, 5, and 6 the slides 17, 17 provide supports forbearing boxes 69 at their lower ends, forming bearing supports for arider roll 70, riding on top of the roll of paper during the windingoperation and maintaining a predetermined pressure nip between the rollof paper and the winder drums 13, 13 and thereby exerting apredetermined force on the roll of paper as it is being wound, whichdecreases as the roll of paper builds up on the winder shaft and isrelieved as the roll of paper 18 built up to a predetermined diameter.The bearing boxes 69 are held in place by bearing caps 94, retained tothe bottoms of the slides 17 as by the machine screws 71.

One rider roll slide 17, shown in FIGURE 4 as being the left hand slide,forms a support for a motor 73 driving the rider roll through V-beltdrives generally indicated by reference character 75. The motor 73 maybe a speed reducer motor in which the speed of rotation of the riderroll may be varied in accordance with the diameter of the roll of paper.The drive to the rider roll is conventional and is no part of thepresent invention so need not herein be shown or described in detail.

As shown in FIGURE 5 each drive chain 66 is connected at one end with aneye bolt 76 extending through and secured to a lug 77 extendingdownwardly of the associated slide 17. From the eye bolt 76 the endlesschain 66 extends upwardly over an idler sprocket 79, suitably journalledin the cap 22, to a control sprocket 80, suitably secured to the outerend of a control shaft 81 extending across the winder and tying the twochains 66, 66 on opposite sides of the machine together, to effectuniform raising and lowering movement of the rider roll. From thecontrol sprocket 80, the chain 66 extends downwardly about an idlersprocket 83 on a shaft 85, mounted at its opposite ends in a clevis 86on the top of the piston rod 68, and secured theretofFrom the idlersprocket 83 the endless chain extends upwardly to and is connected withan eye bolt 88, secured to a ledge 89, formed integrally with the post12 adjacent the upper end thereof.

Extensible movement of the piston rod 68 will thus accommodate loweringmovement of the rider roll 70 downwardly into engagement with theperiphery of the roll of paper being wound on the core shaft 49.

The shaft 85 mounted in the clevis 86 is shown in FIG- URE 6 asextending beyond opposite ends of said clevis and forming a mounting fora counterweight 90 having a hollow central portion 91 opening to theinner side thereof and extending downwardly along the cylinder 67. Asshown in FIGURE 5 the counterweight has an upwardly opening receptacle92 contained therein, extending partially about the cylinder 67 andadapted to be loaded with the lead shot 93 or other weighting means, toprovide the necessary weight to counterbalance the weight of the riderroll 70 and determine the pressure of engagement of the rider roll onthe periphery of the roll of paper, in cooperation with the cylinder 67.

It may be seen from FIGURE 5 that the lead shot 93 may easily beinserted in the receptacle 91 or removed therefrom to the extentrequired to properly balance the rider roll 70. This overcomes theburdensome operation of adjusting the counterweight heretofore presentin drum winders, and makes it possible to rapidly load the counterweightto the required weight for efficient winding requirements.

In operation, shot is loaded in the two counterweights to the extentrequired to initially adjust the counterweight so the system is inequilibrium with the rider roll just touching the roll of paper. Fluidpressure is released from the piston rod ends of the cylinders 67 andfluid pressure fnay be applied to the head ends of said cylinders in theamount required to provide a downward force of the rider roll againstthe roll of paper and create pressure nips between the roll of paper andthe winding drums 13, 13. As the paper is wound on the core shaft, thediameter of the roll of paper will increase and the core shaft will moveupwardly and raise the core shaft slides 17, 17 along the guides 15, 15.Pressure may then be released from the head ends of the cylinders 67 inthe amount required to reduce the pressure of the rider roll on the rollof paper, until such time as the counterweights 91 take over to providea minimum pressure of the rider roll on the roll of paper as the rollreaches its maximum diameter. Pressure may be relieved entirely from theroll of paper by applying fluid under pressure to the piston rod ends ofthe cylinders 67, 67 which may positively lift the rider roll 70 abovethe roll of paper. The control for the rider roll may be an automaticcontrol of a conventional form and is no part of the present inventionso need not herein be shown or described.

While I have herein shown and described one form in which the inventionmay be embodied, it may readily be understood that various variationsand modifications in the invention may be attained without departingfrom the spirit and scope of the novel concepts thereof.
